Hi everybody,
Our SOGo mails are refused by the mail server @orange.fr with the
following error :
"/552 5.2.0 Message contains bare CR and is violating 822.bis section 2.3/"
We've investigated the issue and noticed that this happen everytime we
use a special french character ("à" for example) and/or when we have
several lines in our mail (at least 2 lines).
We also noticed that in such cases, and only in such cases, a header is
added : "Content-Tranfer-Encoding: quoted-printable"
It does not happen when we have a single simple line in our email body
without any special characters.
By the way, we can send attachment without any issue, as long as there
is no "...quoted-printable"
The server is a Debian 11 with Exim4 (4.94.2-7) and SOGo (5.11.2.20241016-1)
Any idea how to solve that issue ?
